Macro to move cursor when cursor is moved to certain column

I am trying to find a way to have set up my worksheet so that when data is entered via scanning a qr code and i get to a certain column the cursor would move back to column A. For example, someone comes up with a name badge with a qr code on it i will scan that data and have it populate into column A2, I will take a tablet that has a qr code on it and scan that data into column B2 and after that scan i want the cursor to move to A3 and for that to continue. Any help would be greatly appreciated. excel help.PNG

This is working just the way i need it to, thanks Kaper it's really really appreciated!
